Extensible Authentication Protocol-Transport Layer Security (EAP-TLS) is an EAP type that is used in certificate-based security environments. If smart cards are used for remote access authentication, EAP-TLS is the required authentication method. The EAP-TLS exchange of messages provides mutual authentication, negotiation of the encryption method, and encrypted key determination between the remote access client and the authenticator. EAP-TLS provides the strongest authentication and key-determination method.
The router could be running outdated and compromised firmware. The router could actually be malicious and actively sniffing packets and logging your data. The router could be improperly configured and other users on the network could be sniffing your data or probing your laptop or mobile device. You never have any guarantee whatsoever that an unknown Wi-Fi hotspot isn’t, either through malice or poor configuration, exposing your data. (A password doesn’t indicate a network is secure, either–even if you have to enter a password, you could be subject to any of these problems.)
The RADIUS server receives a user-connection request from the VPN server and authenticates and authorizes the connection attempt. In addition to a yes or no response to an authentication request, RADIUS can inform the VPN server of other applicable connection parameters for this user such as maximum session time, static IP address assignment, and so on.
As stated previously, most implementations of PPP provide a limited number of authentication methods. EAP is an IETF standard extension to PPP that allows for arbitrary authentication mechanisms for the validation of a PPP connection. EAP was designed to allow the dynamic addition of authentication plug-in modules at both the client and authentication server. This allows vendors to supply a new authentication scheme at any time. EAP provides the highest flexibility in authentication uniqueness and variation.
IVPN doesn’t have as many server locations as larger services like ExpressVPN do. When we initially recommended the service, IVPN was limited to 13 countries, compared with ExpressVPN’s 94. But in the months since, IVPN has doubled that to 26, including two additional locations in Asia (Tokyo and Singapore). We’ve yet to test the new servers though, and in the past, IVPN’s single location in Asia—Hong Kong—was slower than competitors.
We (millennials) have been exposed to the magical world of “gaming”, and wherever we have nothing to do, we start playing games. If you’re an online gamer, you will relate the fact that speed is vital for online gaming. You must have experienced unexpected delays and ping spikes while playing online games; I can sense your pain, there is nothing worse than experiencing delay, lag, and high ping while playing the favorite game online. There are reasons for lag and packet loss; If you try to connect to a long-distance gaming server, then there are chances of being lagged and delayed, highly congested internet service also plays the similar role.
PureVPN has a huge choice of 750 servers in 141 countries and counting. The sheer volume of features, toggles, and tools they provide makes it a top contender for the advanced users. There is a stealth browsing mode, online banking security, secure FTP access, multiple protocols and more. They have server lists optimized for P2P and video streaming, so switching is easy.

It’s up to you to answer these questions by reading over the documentation provided by the VPN service provider before signing up for the service. Better yet, read over their documentation and then search for complaints about the service to ensure that even though they claim they don’t do X, Y, or Z, that users aren’t reporting that they are in fact doing just that.
IP / DNS Leak Test – Security is another crucial factor in my best review process since one of the main purposes of a VPN is to enhance the security of users. Some poor VPN services leak the IP or DNS of the user, which can expose their activities and identity online. It goes without saying that such VPN services are a waste of money and must be avoided at all costs.
Is using the web safely one of your concerns? Maybe you know someone who has been hacked or you’ve experienced it yourself. Have you ever wanted to purchase something or book travel but found it to be more expensive when you revisited it? Do you ever want to download a file but are unsure about your internet security? Or perhaps you’ve wanted to speak to family and friends but feel uncomfortable about how private your connection is. If one or more of these statements are concerns of yours, there is a solution — use a VPN, a way to disguise your IP address and add extra encryption to your data.
Access to restricted websites: Some websites and streaming content may only be accessed in certain countries. For example a TV program might only be broadcast in the UK – Trying to stream this program outside the country will return an error. Through the masking of your IP address, and thus your physical location, free VPN will allow you access to this restricted content and make it appear that you are located in the required region. Learn More

As we already discussed in our guide of high-speed VPNs, VPN vendors use all essential privacy and security protocols to give everyone a safe-house access. However, it is subject to the protocol you use. As mentioned earlier, you need to select a right fast secure VPN protocol depending on your need. Use SSTP and OpenVPN protocols always if you are using torrent or bypassing firewalls like GFW, and NSA protocol. However, if only streaming is your concern, then switch to PPTP and L2TP protocols and get blazing fast VPN speed, with a little compromise on security. PPTP and L2TP are not unsafe, but they have low-security standards layers, that on the other hand, give you top speed for streaming.
In some organization intranets, the data of a department, such as human resources, is so sensitive that the network segment of the department is physically disconnected from the rest of the intranet. While this protects the data of the human resources department, it creates information accessibility problems for authorized users not physically connected to the separate network segment.
A “kill switch” goes by many names, but the term describes VPN software that shuts off all network traffic in and out of your computer if the encrypted connection fails. A hiccup in your Wi-Fi or even with your ISP can cause a VPN to disconnect, and if you then maintain an unsecure connection—especially if the VPN software doesn’t alert you that it’s no longer protecting your traffic—that wipes out all the benefits of your VPN. We considered kill switches to be mandatory. And although we looked for apps that made it easy to add rules about when to activate kill switches, we considered special config files or manual firewall tweaks to be too complex. (iOS doesn’t support any kill-switch features; we address a few iOS-specific problems that apply to all VPN services in a separate section.)
We have also taken into consideration the use of VPN protocols in our fastest VPN trial. All the testing are on PPTP and L2TP connection as they are designed to yield fast VPN performance to the end users. All the high-speed VPN tests are carried out using Speedtest.net, a service that is used by almost everyone to test their internet connection. Below are the baseline speed of our Internet connection without a VPN:
My recommendation, and the protocol I most often choose to use, is OpenVPN. OpenVPN is a non-proprietary, open-source implementation of a VPN communication layer protocol. It's well-understood, well-regarded, generally quite secure, and robust. In addition, it has the benefit of being able to communicate over port 443, which is the standard port for https communication, which means almost all firewalls will allow OpenVPN traffic -- and most won't even be able to detect that a VPN is being used.
ExpressVPN is incredibly fast and super secure, and it can unblock just about any site or service on the internet - including Netflix, Hulu, BBC, and more - with impressive streaming capabilities. It offers servers in over 90 countries, and the 24/7 live chat support is one of the friendliest and most professional. ExpressVPN gives a strong fight to NordVPN, while other VPNs lag behind.
The available speed for each client is unlimited since VPN Express does not impose any restrictions. It is important to clarify that the speed obtained in the navigation will vary according to different parameters such as the own internet provider or the actual physical distance between the client and the chosen server. In terms of downloads, it can be said that they are also unlimited and the provider supports P2P.
Spies—and, more frequently, advertisers—can glean a lot about your movements online. By capturing your IP address, an observer can divine your approximate geographic location. With a VPN it's a different story. Because your web traffic appears to be coming from the VPN's server and not your computer or mobile device (yes, there are Android VPN apps and iPhone VPN apps), any observer will see the VPN server's IP address and not yours. That makes it much harder to correlate your movements across the web.

Voluntary tunneling occurs when a client computer or routing server creates a virtual connection to the target tunnel server. To accomplish this, tunneling client software and the appropriate tunneling protocol must be installed on the client computer. For the protocols discussed in this technical reference, voluntary tunnels require an IP connection (either LAN or dial-up).

We used to advise people to do banking and other important business over their cellular connection when using a mobile device, since it is generally safer than connecting with a public Wi-Fi network. But even that isn't always a safe bet. Researchers have demonstrated how a portable cell tower, such as a femtocell, can be used for malicious ends. The attack hinges on jamming the LTE and 3G bands, which are secured with strong encryption, and forcing devices to connect with a phony tower over the less-secure 2G band. Because the attacker controls the fake tower, he can carry out a man-in-the-middle attack and see all the data passing over the cellular connection. Admittedly, this is an exotic attack, but it's far from impossible.
For PPTP and Layer Two Tunneling Protocol (L2TP), a tunnel is similar to a session. Both of the tunnel endpoints must agree to the tunnel and must negotiate configuration variables, such as address assignment, encryption, or compression parameters. In most cases, data transferred across the tunnel is sent using a datagram-based protocol. A tunnel management protocol is used as the mechanism to create, maintain, and terminate the tunnel.

There are a number of ways to use VPN. The most common scenario is when a remote user accesses a private network across the Internet using a remote access VPN connection. In another scenario, a remote office connects to the corporate network using either a persistent or an on-demand site-to-site VPN connection (also known as a router-to-router VPN connection).
The service’s no logs policy means that it does not store user online activity data and promises not to release them unless required by law, ensuring that your information is in safe hands. What sets this service apart from others is its refund policy. Users are able to use it for up to 10 hours or 10GB of bandwith and still get a refund, a far more generous policy than what others have to offer.

IP / DNS leak test – IPVanish does not suffer from any DNS or IP leak problems. This is a sign of the strong security and encryption protocols that IPVanish uses. As such, you can download torrents through IPVanish and rest assured that your IP won’t be leaked. However, in spite of the solid security, I still wouldn’t recommend going the torrent route with IPVanish for reasons highlighted below.
However, if you’re using a top-tier VPN service, the difference in speed usually isn’t noticeable, and can sometimes speed up your connection. You can still watch streaming videos and download large files without interruption. Our VPN servers are among the fastest in the industry and we work hard to keep it that way. Download Hotspot Shield VPN and get privacy protection without sacrificing speed.
When we test VPNs, we generally start with the Windows client. This is often the most complete review, covering several different platforms as well as the service's features and pricing in depth. That's purely out of necessity, since most of our readers use Windows (although this writer is currently using a MacBook Air). We currently use a Lenovo ThinkPad T460s laptop running the latest version of Windows 10. We periodically upgrade to a newer machine, in order to simulate what most users experience.
Each internet request usually results in a whole series of communication events between multiple points. The way a VPN works is by encrypting those packets at the originating point, often hiding not only the data, but also the information about your originating IP address. The VPN software on your end then sends those packets to VPN server at some destination point, decrypting that information.
TorGuard’s signup and payment process is also fine but not stellar. Compared with that of IVPN, the checkout process is clunky, and using a credit or debit card requires entering more personal information than with our top pick. The easiest option for anonymous payments is a prepaid debit card bought locally. Otherwise, like most providers, TorGuard accepts a variety of cryptocurrencies, PayPal, and foreign payments through Paymentwall. That last service also allows you to submit payment through gift cards from other major retailers. We don’t think this method is worth the hassle for most people, but if you have some money on a fast-food gift card you don’t want, turning it into a VPN service is a nice option.
Some VPN services will limit the total amount of data you can send and receive, either in one connection session or over the period of a month. Other VPN services will limit the speed of the data, effectively sharing less of their pipe with you than might be optimal. That could slow your browsing experience to a crawl or completely prevent you from watching streaming video.
GRE is sometimes used by ISPs to forward routing information within an ISP's network. To prevent the routing information from being forwarded to Internet backbone routers, ISPs filter out GRE traffic on the interfaces connected to the Internet backbone. As a result of this filtering, PPTP tunnels can be created using PPTP control messages, but tunneled PPTP data is not forwarded.

Authentication that occurs during the creation of a PPTP-based VPN connection uses the same authentication mechanisms as PPP connections, such as Extensible Authentication Protocol (EAP), Microsoft Challenge-Handshake Authentication Protocol (MS-CHAP), Microsoft Challenge-Handshake Authentication Protocol version 2 (MS-CHAP v2), CHAP, Shiva Password Authentication Protocol (SPAP), and Password Authentication Protocol (PAP). PPTP inherits encryption, compression, or both of PPP payloads from PPP. For PPTP connections, EAP-Transport Layer Security (EAP-TLS), MS-CHAP, or MS-CHAP v2 must be used for the PPP payloads to be encrypted using Microsoft Point-to-Point Encryption (MPPE).
VPNs, or Virtual Private Networks, are a quick and easy solution to making your computer appear to be coming from a different location. They accomplish this by creating a virtual network that routes all of your PC or smartphone’s network traffic through an encrypted tunnel and out the other side, making it seem to the world that you’re actually in whatever location the VPN server is located. This can help you bypass geographic restrictions, avoid censors, or keep you (relatively) anonymous online.
Our next pick for best VPN of 2018 is IPVanish. The service permits torrenting and throws in a free Smart DNS service for all customers. The biggest downside is that it’s based in the US —not an ideal location since the NSA is notorious for its intensive and often illegal surveillance. To combat this, IPVanish doesn’t keep logs and does provide DNS leak protection. Despite being a little stripped-down, works very well.
Our Findings: During the test we found HMA delivering a pretty decent volume of speed. However, we noticed a bit of throttling and interruptions in the connection. Overall, the fast VPN test was fine, and we didn’t experience much downstream. We discovered that due to highly encrypted protocols tied up with HideMyAss network, its connection is slow compare to ExpressVPN and IPVanish.
You might be thinking: “I only need one connection, don’t I?” What if you want to set up VPN access on more than one device, for more than one family member, on your home router, or the like? You’ll need multiple concurrent connections to the service. Or, perhaps, if you’re particularly security oriented, you’d like to configure multiple devices to use multiple different exit nodes so your collective personal or household traffic isn’t all bundled together.

L2TP/IPsec (Layer 2 Tunneling Protocol with Internet Protocol Security): L2TP is not secure itself, so it's generally paired with the IPsec secure-networking standard. The combination of the two was once thought to be very secure when properly implemented, but some VPN services suggest that you use OpenVPN instead. L2TP/IPsec has native support in Windows, OS X/macOS, Android, Chrome OS and iOS. Most VPN services support it.


While privacy should be the number one deciding factor when choosing a VPN service, performance and speed are also a necessity. Our team has engineered TorGuard to provide the highest levels of security and speed from anywhere in the world. Regardless of whether you are connecting from North or South America, Europe, Asia or Oceania, our worldwide VPN network will provide you the fastest speeds possible from anywhere around the globe. TorGuard maintains 50+ VPN server locations with 3000+ Servers and our network is always expanding.
To stress-test the VPN services, we do things a little differently. Instead of letting Ookla find the best (read: closest) test server, we select a specific test server in Anchorage, Alaska, for both the VPN testing and the baseline test. We then connect to a VPN server in Australia, and calculate a percent change between the two. Usually, this results in a noticeable impact on latency as well as download and upload speeds. It helps give a sense of how the VPN would perform when you're traveling abroad or using the VPN to spoof your location.
Jurisdiction – PureVPN has a fairly strong jurisdictional advantage. Hong-Kong is far from the watchful eyes of European governments and the 14 Eyes alliance. The state of the Internet in Hong Kong is one of the freest in the world. The government in Hong-Kong does not sweep online content under the rug of censorship. However, acts like distribution of child pornography are criminalized (as they should) by law and fall under the cloak of censorship. So, the jurisdiction of PureVPN should be a reason enough to compel privacy-conscious users to get this VPN.
Everyone wants to keep their browsing activity safe and secure, but not at the expense of compromising on speed, right? This is where a fastest VPN service comes in. But why there’s a need for a fast VPN, don’t you trust your Internet provider? This WHY has multiple answers, but the best to quote here is that VPN slows down the internet, seriously? Yes, depends on the VPN you’re using. People all around the world use VPN services not only for their security but for various other entertainment purposes like streaming and downloading torrents. They look for the fastest VPN which not only keeps their browsing activity safe but also let them be the fastest on the radar.

For features, they offer multi-hop VPN cascades, advanced firewall configuration options (DNS and IP leak protection), port forwarding, NeuroRouting, Socks5 and Squid proxies, obfuscation features to defeat VPN blocking (Stealth VPN), and a customizable TrackStop feature to block tracking, malware, advertising and social media domains. They also give you an unlimited number of device connections and offer full IPv6 support across their server network.
Likewise, if you're connecting via a nation's local carrier, that carrier may be intercepting your traffic, particularly if you're a non-native of that nation. In that situation, if you must connect back to applications and services at home, using a VPN is quite literally the least you can do. Also, keep in mind that if you use your phone's hotspot to connect your computer to the internet, you'll want to use a VPN on your computer as well.
A traditional VPN can affect the user experience when applied to wireless devices. It's best to use a mobile VPN to avoid slower speeds and data loss. A mobile VPN offers you a high level of security for the challenges of wireless communication. It can provide mobile devices with secure access to network resources and software applications on their wireless networks. It's good to use when you're facing coverage gaps, inter-network roaming, bandwidth issues, or limited battery life, memory or processing power.
Windscribe has always been one of our favorite free VPNs. Compared to other free services, Windscribe gives you more – 10GB data allowance per month! This is pretty amazing because Windscribe is actually trying to encourage people to buy its premium service. What’s more, this VPN has strong encryption and keeps zero logs – making it fantastic for privacy. With unlimited simultaneous connections permitted, this VPN is truly outstanding.
Jurisdiction – Gibraltar is territory that is controlled by the United Kingdom to some extent. Nonetheless, the internal affairs of the country are governed by itself. Censorship of certain websites is present in Gibraltar. As such, the jurisdiction of IVPN lies in a region with limited online freedom, but privacy in the region is still much better than in Europe.
Some VPNs offer great service or pricing but little to no insight into who exactly is handling them. We considered feedback from security experts, including the information security team at The New York Times (parent company of Wirecutter), about whether you could trust even the most appealing VPN if the company wasn’t willing to disclose who stood behind it. After careful consideration, we decided we’d rather give up other positives—like faster speeds or extra convenience features—if it meant knowing who led or owned the company providing our connections. Given the explosion of companies offering VPN services and the trivial nature of setting one up as a scam, having a public-facing leadership team—especially one with a long history of actively fighting for online privacy and security—is the most concrete way a company can build trust.
My recommendation, and the protocol I most often choose to use, is OpenVPN. OpenVPN is a non-proprietary, open-source implementation of a VPN communication layer protocol. It's well-understood, well-regarded, generally quite secure, and robust. In addition, it has the benefit of being able to communicate over port 443, which is the standard port for https communication, which means almost all firewalls will allow OpenVPN traffic -- and most won't even be able to detect that a VPN is being used.
Nevertheless, the point of a VPN is to remain private and to have your internet activity kept as private as possible. For that reason, we’re choosing Mullvad as the best overall VPN (see our full review of Mullvad). The interface needs a lot of work, but the company does a great job at privacy. Mullvad doesn’t ask for your email address, and you can mail your payment in cash if you want to. Like many other VPNs, Mullvad has a no-logging policy and doesn’t even collect any identifying metadata from your usage.
Perfect Privacy holds the top spot as the best VPN for advanced online anonymity. While it may be overkill for basic users, this is a powerful VPN with advanced online anonymity features you will not find anywhere else. It is a well-regarded service that has earned high praise from the tech community for exposing vulnerabilities and flaws other VPN providers.
IPVanish is one of the very best and reliable VPN service providers with an extensive range of VPN servers in more than 60 countries. The wide range of server availability (more than 500 servers) makes their credibility stronger to be in the fastest VPN service provider list. IPVanish is also known as a Tier-1 VPN provider with all the required and advanced VPN features to offer. As a fast VPN option, it offers unlimited bandwidth that is best for all streaming lovers and other netizens. Not only this, but IPVanish has some remarkable features like KillSwitch, unlimited server switching and automatic IP-scrambler that makes a fast VPN connection. With IPVanish you can get your money back within 7 days in case you are not fully satisfied with their fast VPN connection. Here is the VPN speed test result for IPVanish:
VPN services offer up different "gateway" cities, allowing you to choose where the IP address assigned to your computer is located. This allows you to access websites typically only available to users from that country. It also allows you to access websites that may blocked/censored in your own country. This application is particularly important for travelers who need to access websites from their home country, as well as for people living in regions rife with Internet censorship, such as China and Iran.
Advanced leak protection – Perfect Privacy offers very secure apps to ensure you are protected against any and all leaks. In the Perfect Privacy review I discuss the three different levels of the kill switch and DNS leak protection. Users are also protected from IPv6 leaks because Perfect Privacy offers full IPv6 support across their server network (giving you both an IPv4 and IPv6 address for all your devices).

Well, the pace of life is getting faster, the internet is getting faster, our smartphones are getting smarter and of course, FASTER! But when it comes to VPNs, the science doesn’t really work the same way. VPN is used primarily for security reasons, and it’s a fact that when you add or increase encryption to your internet connection, you would face speed reduction. No matter you choose the speediest VPN service out there that claims they have “Super-Fast VPN servers” if there is encryption implied to your online data packets, your internet connection speed would get a little slow because of the encryption and decryption taking place. But it usually gets unnoticed or you won’t feel much difference in browsing as most of the reputable and fast VPN services make the whole experience look effortless.


I don't get this rush to VPN's - especially free VPN's. The overwhelming majority of us are not dissidents hiding under the radar. Sure, we all like our privacy, but I believe it's sheer fantasy to think that "free" VPN providers are just somehow more trustworthy than internet providers (ISP's), who are at least getting paid by us, the internet subscribers.
There are a number of ways to use VPN. The most common scenario is when a remote user accesses a private network across the Internet using a remote access VPN connection. In another scenario, a remote office connects to the corporate network using either a persistent or an on-demand site-to-site VPN connection (also known as a router-to-router VPN connection).

This is important to understand. Consumer VPN services protect your transmission from your location to their location, not from your location all the way to the destination application you're using. If you think about it, this makes sense: A consumer VPN service is operated by a completely different company than, for example, Facebook or your bank.
The user’s certificate could be stored on the VPN client computer or in an external smart card. In either case, the certificate cannot be accessed without some form of user identification (PIN number or name/password credentials) between the user and the client computer. This approach meets the something-you-know-plus-something-you-have criteria recommended by most security experts.
It is our business to make safety and caution for our free VPN service the number one priority. We are constantly working to understand and develop new technology that keeps our users safe, without requiring costly fees or lengthy sign-up features. We want to keep you and your family safe without you having to give up any freedom. We would never limit these rights and don’t believe in setting limits. That is not our business.
